LQQKING DEVICE FOR CYCLE AND SIMILAR LAMP BRACKETS.

Application filed December 6, 1926, Serial No. 152,872, and in Great Britain November 23, 1925.

, This invention relates to improvements in cycle and similar lamp brackets and consists of providing a locking device for preventing the theft of cycle or similar suspended lamps.

Many forms of such lamp brackets have been suggested and of these a bracket has been proposed in which the port-ion of the bracket which enters the lamp socket is con structed long enough to protrude some dis- 1o tance through same and the protruding end is designed to receive a head carrying a spring lock which can only be removed by the use of a key.

The present invention is an adaptation of the last mentioned bracket. The bracket is provided with a tongue extension coplanar therewith having a' series of wards along one of its edges and of such dimensions as will allow of the extension being readily passed through the lamp socket.

In order to prevent removal of the lamp from this bracket a locking member is provided in the form of the barrel portion of a permutation lock carrying tumblers of larger 26 external diameter than the aperture of the lamp socket; This lock is placed upon the protruding end of the tongue when the lamp is in posit-ion on the bracket.

My invention is illustrated by way of ex- 30 ample in the accompanying drawings, in

which- Figure 1 shows a bracket with a. vertical tongue extension adapted to receive the permutation lock, and

designated by the same reference characters Figure 2 shows an alternative form in which a horizontal tongue is employed.

Referring now to the drawings; 1 indicates the bracket, and 2 the extension provided with a series of wards 3 along one edge. The tongue 2 is adapted to receive the mem- 40 her carrying the tumblers of the permutation lock 4, the tumblers being of a larger external diameter than the aperture of the lamp socket. Any suitable type of permutation lock can be employed and its operation requires no description.

Figure 2 shows a modification in which the tongue extension 2 is horizontal. The parts which correspond with those in Figure 1 are primed.

Finally it should be mentioned that I am aware that permutation locks for such purposes as locking handle bars of bicycles, have been suggested.

What I claim is The combination of a brackethaving an integral tongue extension provided with a
